开源项目介绍-02 Aubio【1】环境配置和使用 @ Ubuntu + Pycharm + Python-易微帮

前言：

aubio 是一组算法和工具，用于标记和变换音乐和声音。它扫描或监听音频信号，并尝试识别音乐事件。例如，当鼓被击打时，它能检测到音符的频率，或者一个有节奏的旋律的节拍是多少。

aubio 的功能包括：

在每次打击前对声音文件进行分割
进行音高检测
敲击节奏
从现场音频产生 MIDI 流
Python版本的配置和使用：
按照官网的说法，异常简单，但是,。。。。。

笔者的工作目录：github,下载后解压，

K:\Prj_EDU\Sw_Proj\Aubio_python

1 python + pycharm 版本@windows：【失败】

$ python -c "import aubio; print(aubio.version, aubio.float_type)"

如果没有安装：

1.1 安装AUBIO

1.1.0 用pip安装aubio，错误，笔者没有实现：

错误如下：

2 Python版本 pycharm @Linux Ubuntu的版本【成功】

项目地址：

frank@frank-virtual-machine:~/Projects/PythonAubio/PrjAubio$

2.1 在ubuntu上安装pycharm（略）

2.2 配置环境：

2.2.1 安装numpy

 pip install numpy

遇到问题：

(.venv) frank@frank-virtual-machine:~/Projects/PythonAubio/PrjAubio$ pip install numpy

ERROR: Could not find a version that satisfies the requirement numpy (from versions: none)
ERROR: No matching distribution found for numpy

解决：

1 安装 python-pip

sudo apt-get install python-pip

2 用pip安装numpy,并采用清华的安装包源：

pip install numpy -i https://pypi.tuna.tsinghua.edu.cn/simple

【案]如果直接用pip install numpy 会报错：

2.2.2 直接安装：aubio

pip install aubio

2.3.2 使用python版本的工具：

2.3.2.1 py确认系统安装的python的可用版本

2.3.2.2 运行一个demo

报错，audio的图像画的时候，确实python, matplotlib包：

2.3.2.3 安装matplotlib

(.venv) frank@frank-virtual-machine:~/Projects/aubio/aubio/python/demos$ pip install matplotlib
ERROR: Could not find a version that satisfies the requirement matplotlib (from versions: none)
ERROR: No matching distribution found for matplotlib

[notice] A new release of pip is available: 23.2.1 -> 24.0
[notice] To update, run: pip install --upgrade pip

提升pip的版本有点低，

解决，先sudo apt update更新包的List，

然后，sudo apt install python3-pip

【案] linux 系统的好处，就是配置开源环境的时候，比windows的系统，方便太多，

然后，安装matplotlib

(.venv) frank@frank-virtual-machine:~/Projects/aubio/aubio/python/demos$ pip3 install matplotlib

【案，由于源的问题，会报错】

改为，

pip3 install -i https://pypi.mirrors.ustc.edu.cn/simple/ matplotlib

2.3.3 使用demo_notes。py 找到一段音乐的音调：

【案，笔者先录制了一段D4调号的钢琴音乐，然后，用识别软件进行测试，结果如下]

(.venv) frank@frank-virtual-machine:~/Projects/aubio/aubio/python/demos$ python3 demo_notes.py TestAudio/1_D4.wav

由此，LINUX环境下的配置成功完结。

aubio

=====

aubio is a collection of tools for music and audio analysis.

This package integrates the aubio library with [NumPy] to provide a set of

efficient tools to process and analyse audio signals, including:

- read audio from any media file, including videos and remote streams

- high quality phase vocoder, spectral filterbanks, and linear filters

- Mel-Frequency Cepstrum Coefficients and standard spectral descriptors

- detection of note attacks (onset)

- pitch tracking (fundamental frequency estimation)

- beat detection and tempo tracking

aubio works with both Python 2 and Python 3.

Links

-----

- [module documentation][doc_python]

- [installation instructions][doc_python_install]

- [aubio manual][manual]

- [aubio homepage][homepage]

- [issue tracker][bugtracker]

Demos

-----

Some examples are available in the [`python/demos` folder][demos_dir]. Each

script is a command line program which accepts one ore more argument.

**Notes**: installing additional modules is required to run some of the demos.

### Analysis

- `demo_source.py` uses aubio to read audio samples from media files

- `demo_onset_plot.py` detects attacks in a sound file and plots the results

using [matplotlib]

- `demo_pitch.py` looks for fundamental frequency in a sound file and plots the

results using [matplotlib]

- `demo_spectrogram.py`, `demo_specdesc.py`, `demo_mfcc.py` for spectral

analysis.

### Real-time

- `demo_pyaudio.py` and `demo_tapthebeat.py` use [pyaudio]

- `demo_pysoundcard_play.py`, `demo_pysoundcard.py` use [PySoundCard]

- `demo_alsa.py` uses [pyalsaaudio]

### Others

- `demo_timestretch.py` can change the duration of an input file and write the

new sound to disk,

- `demo_wav2midi.py` detects the notes in a file and uses [mido] to write the

results into a MIDI file

### Example

Use `demo_timestretch_online.py` to slow down `loop.wav`, write the results in

`stretched_loop.wav`:

$ python demo_timestretch_online.py loop.wav stretched_loop.wav 0.92

Built with

----------

The core of aubio is written in C for portability and speed. In addition to

[NumPy], aubio can be optionally built to use one or more of the following

libraries:

- media file reading:

- [ffmpeg] / [avcodec] to decode and read audio from almost any format,

- [libsndfile] to read audio from uncompressed sound files,

- [libsamplerate] to re-sample audio signals,

- [CoreAudio] to read all media formats supported by macOS, iOS, and tvOS.

- hardware acceleration:

- [Atlas] and [Blas], for accelerated vector and matrix computations,

- [fftw3], to compute fast Fourier Transforms of any size,

- [Accelerate] for accelerated FFT and matrix computations (macOS/iOS),

- [Intel IPP], accelerated vector computation and FFT implementation.
